title: Reactivation of chicken erythrocyte nuclei in heterokaryons results in expression of adult chicken globin genes.
abstract: Activation of chicken globin gene transcription has been demonstrated in chicken erythrocyte--rat L6 myoblast heterokaryons. The globin mRNA is polyadenylylated and is translated into adult chicken alpha A-, alpha D-, and beta-globin polypeptides. No fetal globin mRNA or globin polypeptides were detected. Heterokaryons between chicken erythrocytes and mouse neuroblastoma cells or hamster BHK cells also synthesized adult chicken globins.
